I have an ADV7612 without the HDCP core as my company is not licensed for HDCP. As such the part outputs a black raster when encrypted HDMI is input. However I'd like to let users know when an HDCP signal is present, and I see that there is a register called HDMI_CONTENT_ENCRYPTED - Main Addr, Reg Addr 0x05. However this register always tells me that the input is unencrypted. I'm guessing that this part has the HDCP core depopulated, and as such all of these registers are non-functional? Can someone please clarify that there is no way of determining HDCP presence on a non-hdcp enabled ADV7612?
